BALL-COCK FOR. FLUSH-TANKS.

To alllwhom it may concern: l

Be 1t known that I, EDWARDA GEHRKE, a

Vcitizen of the United States, residing at Lini accidents.

vAnother object of the' invention is to provide a ball cock having a straining device and equipped with an efficient catch basin,

adapted to drain when the main water supply is cutoff.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, villustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that variouschanges in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing :-F igure 1 is a vertical sectional view of a ball cock, constructed in accordance with this invention and shown applied to a portion` of a flush tank. Fig. 2 is a horizontal sectional view on the line 2 2 of Fig. 1. Fig. 3 is a vertical sectional view cn the line 3-3 ofFig. 2,.

' Like numerals of reference designate corresponding parts in all the figures of the drawing.

In the accompanying drawing in which is illustrated the preferred yemlmdiinent of the invention, 1 designates a ball cock body arranged horiZontally-and provided at one end with astrajght depending tubular discharge arm 2 and. having a laterally projecting downwardly extending tubular inlet arm or elbow 8, connected with the said end of the body at a point above and beyond the .tubular discharge arm 2. The body -1 is provided with an interiorly arranged partition 4, extending upwardly froint-he outer side of the 'discharge arm 2 to"the top of the body and i specification of Letters Patent.

` Patented sept. 15, 1914. serial No. 791,065.

separating the inlet and discharge arms and 'provided with a threaded openingv 5, arranged concentric with the axis'of the body portion 1 and receiving an exteriorly thread`v ed tubular valve seat 6, capable of adjustment and arranged to be engaged by a heavy rubber washer 7, which is carried by a shaft 8. The tubular adjustable `valve seat, which is designed to be constructed of copper bronze or any other suitable material, is

adapted to be made of a better and harder material than the body of the ball cock, and.

it thereby increases the durability of the same. vThe tubular valve seat is provided with opposite interior lugs or enlargements 9, .adapted to be engaged by a suitable tool when the shaft 8 is removed, whereby the valve seat may be adjusted without detaching the body.

The body, 1 is'provided with coarse interiorly arranged screw threads 10, which are engaged by coarse exterior threads 11 formed on an enlargement 12 of the shaft 8 and adapted to produce a quick action of the Iball cock. The enlargement is located at an intermediate point between the .ends of the shaft, which is provided at its inner end with a head 13, having a circular recess M .'to receive the heavy rubber was/her 7, which is secured in the recess by a screw 15. The screw -15 extends through a central opening of the washer and engages' a threaded bore 16 in the inner end of the shaft 8. The outer portion of the shaft receives an inner metal washer 17, which is arranged in an interior annular recess 18 at the front end of the body 1,' which is provided with exterior screw threads 19 for engaging interior threads of a cap 20. The cap 20, which forms a stuffing box and receivesa suitable packing 21,'has a central opening 20'El for the outer portion of the shaft 8 and-is provided with an interior annular recess 22 located at the inner end of the interiorly threaded portion of the cap and receiving a washer 23 of fiber or other suitable material. The washer 23, which is of greater diameter than the washer 17, fits against the outer face of the same and extends beyond the joint, the outer washer overlapping the joint between the same and the front end of the body 1.

` The outer end 24 of the shaft is i'ectanguf lar in cross section'a-nd tapered to lit a correspondingly shaped polygonal opening 25 of an arm 26, secured on the tapered end 24' the bottom 33 ot' the vflush tank.

of the shaft 9 by a screw 2T engaging a threaded bore 2S of the said shaft. The arm 26, which is arranged at right angles to the shaft, extends therefrom and is provided at its outer end with an interiorly threaded socket 29 for the reception of a rod 30 of a oat 31, which is preferably in the orm of a ball. The float is adapted to rise and fallin 'is secured a relatively small discharge pipe 35 to furnish water for the afterliow or water seal following the lusliing of the closet.

lThe elbow arm 3 is interiorly threaded to receive the upper end of a vertical pipe or tube 36, which is interiorly threaded to receive a strainer 37,A consisting of a disk of suitable straining material secured to an exteriorly threaded sleeve 38, which engages the interior threads of the main pipe or tube 36. The lower end 39 of the main pipe or tube is exteriorly threaded to screw into the upper interiorly threaded end 40 of a short coupling tube or section 41, which extends through the bottom 33 of the flush tank. `lhe coupling tube or section 41 is provided with an interior annular flange 42, forming a stop for the lower end of the main Vertical tube 3G and provided with a threaded opening in which is ,mounted a short inner vertical tube 44, spaced from the interior of the main vertical tube 36 and forming an annular inner space and providing a catch basin tor sediment strained by the strainer 37. rlhe lowerend 45 oftheinner vertical tube is threaded to engage thel threads of the interior flange 42, and the said tube 44 is provided at the upper face of the flange 42 with a drain opening 46 for draining the catch basin when the main water supply is cutoff.

rllhe coupling tube or section 4l projects below the bottom of the flush tank and is exteriorly threaded at 47 for the attachment ot a water supply pipe 48. The coupling tube or section is provided at the upper face of the bottom 33 with an integral exterior annular flange 49 and the exterior threads of the lower poi'tion47 receive a threaded collar or nut 50, 1"dich coacts with the iange 49 in clamping the bottom 33 of the flush tank. An elastic gasket 51 is interposed between the nut 50 and the bottom 33 of the Hush tank to take care of any shrinking or swelling of' the bottoni whenr the flush tank is constructed of wood.

that is claimed is 1. ln combination .with a flush tank, of a coupling section piercing the bottom of the flush tank and having means for engaging the same and provided with an interior iange having an opening,`a main vertical tube mounted within the upper portion of the coupling section and having its upper end interiorlyl and exteriorly threaded, a strainer engaging the interior threads ot the main tube, a ball cock mounted on the upper end of the main tube and engaging the exterior threads thereof, and an inner vertical tube mounted in the opening ot the said ilange and extending intothe lower portion o1e the main vertical tube and spaced therefrom to form a catch basin, said inner vertical tube being provided above the flange with a drain opening.

2. The combination with a iiush tan-k, of a coupling section piercing the bottom oi2 the fiiish tank and provided with means for engaging the `saine and having an upper projectmg portion, said upper projecting portion being provided with an interior iiange having an opening, a main vertical tube mounted in the upper projecting portion of the coupling section and seated upon the said flange, and an inner vertical tube secured inthe opening of the said liange and extending upwardly into the main vertical tube and arranged in spaced relation with the saine to Storni a catch basin, said inner vertical tube having a drain opening and the said tubes being removable from the coupling section with out detaching the latter from the iiush tank.

In testimony, that I claim the foregoing as my own, I 'have hereto aiiixed my signature in the presence of two witnesses.
